Which organ is primarily responsible for bile storage?

The gall bladder is primarily responsible for bile storage. It is a small, pear-shaped organ located beneath the liver that stores and concentrates bile produced by the liver. Bile is essential for the digestion and absorption of fats in the small intestine. When food containing fat enters the small intestine, hormonal signals prompt the gall bladder to contract and release the stored bile into the duodenum, aiding in the digestive process.

While the liver produces bile, it does not store it; rather, it secretes bile continuously. The kidneys are involved in filtering blood and producing urine, while the spleen plays a role in filtering blood and recycling iron from red blood cells. These organs do not have the function of storing bile, which is why the gall bladder is the correct choice.
